The VRE410 is a low cost, high precision, ±10V reference. Recommended for D/A and A/D converters which require and external precision reference. The device provides ultra-stable ±10V output with ±1.6mV initial accuracy and a temperature coefficient of 1.0 ppm/°C. This improvement in accuracy is made possible by a unique, patented multipoint laser compensation technique. Another key feature of this reference is the 3mV tracking error between the positive and negative output voltages over the full operating temperature range. This is extremely important in high performance systems for reducing overall system errors.
